Fuel cell stack comprises several fuel cells (2) of the polymer-electrolyte membrane structure to form the stack, and parallel channels (8) for a cooling fluid arranged between neighboring membrane electrode units (4, 5, 6). The through-flow of neighboring...

The fuel cell arrangement has at least two fuel cell stacks (1,2) formed of polymer electrolyte membrane fuel cells at a distance apart and an arrangement that feeds air required for the delivery of oxygen through the stacks. The air is fed in a partially ...

The cell or arrangement has a gas-tight and ion transmitting cell membrane (7) per cell, an anode on one side of the membrane and a cathode on the other side, a gas diffusion layer (4,11) and a bipolar or end plate (1) on each side of the membrane and a su...

End plate arrangement for electrochemical cell of polymer electrolyte type, especially cell stack, includes: (a) plastics or metal end plate introduced into cell or cell stack under compressive force; (b) electrically conducting layer, on cell-facing surfa...
